3 Claims.

This invention relates to a package.

The object of the invention is to provide a novel and improved lined package in which provision is made for closing and sealing the mouth of the liner in a novel and improved manner.

With this general object in view and such other as may hereinafter appear, the invention consists in the package hereinafter described and particularly defined in the claims at the end of this specification.

In the drawing illustrating the preferred embodiment of the invention, Fig. 1 is a perspective view of a lined package embodying the present invention showing the form of top closure for the mouth of the lining; showing the folded closure laid against the top of the package; Fig. 3 is a perspective view illustrating the manner in which the mouth of the lining is spread and provided with adhesive together with one of the carton closing flaps to form a sealed closure for the lining; and Fig. 4 is a cross-sectional view through the package illustrated in Fig. 3 showing the construction after it has been closed and sealed.

In general, the ticular use in the production of a lined package comprising a lined carton having a novel and improved top closure which is characterized by the,,:provision of but two opposed closing flaps forthe top of the carton and in which the mouth of the lining is provided with a closure such as to reduce to a minimum the liability of leakage of the material therethrough. A preferred form of top closure for the mouth of the lining bag may be formed by folding inwardly two opposed end portions of the extended top of the lining bag to form a pleated closure, the mouth portion of which may be sealed in a novel manner to effectively enclose the contents of the lining bag.-

In practice, such top closures for the mouth of the lining bag are preferably performed by suitable mechanism in a packaging machine while the bag is supported in'the outer container or car- 0011. When, as heretofore, the lining closure is performed while the bag is supported in the conventional carton provided with the usual four top closing flaps comprising two opposed end flaps and two opposed side flaps, several difficulties are encountered and disadvantages result from the presence of the two opposed narrow end flaps of the carton. In practice, the mechanism for performing the top folding operations of the mouth of the lining must of necessity be disposed so as to sweep through the path of the top closing flaps of the carton so that means for Fig. 2 is a similar view present invention finds par- July 14,

flaps outwardly and for retaining them in this position during the folding operation had to be provided.

In accordance with the present invention, the carton is provided with but two opposed top closing flaps, the'narrower opposed flaps being eliminated, whereby to enable such top closures to be more readily and conveniently performed upon existing machines in which the mechanism for bending the end flaps outwardly'may be eliminated. In addition, the elimination of the two opposed narrow end closing flaps serves to reduce the bulk or thickness of'the completed top closure thus enabling a neater appearing package to be produced.

In order to effectively seal the carton at the ends where the closing flaps are omitted, the present carton is provided with sealing wings upon one of the remaining side flaps which are arranged to close over the adjacent edges of the carton to form a relatively tight and eflicient seal for the top of the carton,

Referring now to the drawing, [0 represents a package or carton provided with but two opposed closing flaps l2, M, the latter being provided with end sealing wings l6, I8. The package is provided with a suitable inner liner or bag 20 with-,

in the carton, and the mouth of the lining is arranged to project above the top of the opened package, as illustrated in dotted lines in Fig. 1. The illustrated top closure for the mouth of the lining bag 2!! may be formed by folding inwardly two opposed portions of the extended mouth of the lining bag and then bringing together the remaining two opposite sides to form an upstanding closure or tab 30 as shown in Fig. 1. The upstanding tab portion 30 of the closure is then folded down into engagement with the top of the package with the upper or mouth portion 32 thereof extending over the edge of the container and resting upon a part of the side flap l2 as shown in Fig. 2.

In practice, the carton is then passed through suitable adhesive applying mechanism to provide a coating of adhesive over the entire inner surface of the carton side flap I2, and upon the inner surfaces of the sealing Wings l6, l8 of the side flap I4. The side nap I4 is then folded inwardly over the top of the closed lining bag and the sealing wings l6, I8 are folded down and pressed into sealing engagement withthe' adjacent panels of the carton as shown in Fig. 3. Finally, the remaining carton flap i2 is closed over the flap l4 and pressed into sealing engagebending the 66 ment therewith to provide the completely sealed package as shown inFig. 4. Thus, an emcient claimed is 1' and eflective top closure for the lining and the narrow end flaps of the carton. V

In order to provide a sealed closure for the 'carton is provided without the use of the usual mouth portion 32 of the lining in asimple and.

eflicient manner, the mouth portion extending beyond thegedge oi the closed'i'laprll maybe spread apart; as shown'in Fig. 3, one half resting flat on top of the flap H and the other half resting on the extended flap i2. With the top closing members in this: condition, therpackage maybe passed through the standard adhesive applying mechanism to provide adhesive simultaneously over the inner surface of the 'flap l2 and upon the extended half of the mouth portion 32. Thereafter the'fiap I2 is folded over on top or the flap I4, thus also ielding the adhesively coated half of the mouth portion I2 7 into contact with the opposing half and forming a sealed closure for the mouth of the lining. As

: illustrated in Fig.4, the construction ofthecompletely closed and sealed package 'providesan interlocking or the mouth or the lining between the upper vandlower flaps 12, l4 and enables wan adhesive seal to'be provided tor the mouth portion of the lining simultaneously withthe adhesive sealing of the top flap 12 into engage- -ment with thefiap l4..- In addition, a positive [seal is vefiected alongthe'opposed edges of the vcarton where the end flaps are omitted, by the provision offthe sealing wings I 6, 18, as above described From the above descriptionfitjwillbe seen that the construction oi the present package issuch as to facilitate the performance of the top clos ing operation forthe mouth of the lining and enables an efiicient carton closure to be made in a manner such as to'efiectively seal the con- 7 tents of the containerin a novel and improved manner with but;two of the usual iour carton -While the preferred embodiment of the inven- 7 tion has been hereinillustrated and described, it

- will be understood that the invention. maybe embodied in other iorms within the scopeof the] following claims. a
